These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.

Zinc-plated steel locknuts resist corrosion in wet environments.

Half the height of standard nylon-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. These nuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut. All have a finish that resists corrosion in wet environments.

These locknuts have good chemical resistance and may be mildly magnetic. They're about half the height of standard nylon-insert locknuts. Use them in low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.

These locknuts are about half the height and 10% wider than standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against an extra-wide hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. A zinc plating provides mild corrosion resistance in wet environments.

These locknuts are about 10% wider and taller than standard nylon-insert locknuts and distribute the load over a large area. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Use them in light duty fastening applications, such as securing access panels. A zinc plating provides corrosion resistance in wet environments.

An irregularly shaped thread at the top of the nut grips the bolt for a stronger hold than nylon-insert locknuts. They thread on from the bottom of the nut, allowing more threads to engage the bolt before tightening for easier installation than center-lock distorted thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable. Comparable in strength to Grade 8 bolts, they're about 25% stronger than medium-strength steel locknuts.

Zinc-plated and zinc yellow-chromate plated locknuts resist corrosion in wet environments.

When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration. These locknuts are often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 5 steel, they're suitable for fastening most machinery and equipment.
